Answer:
The final temperature is equal to 240 K or -33.15°C
Explanation:
Given that,
Initial temperature of the gas, T₁ = 47°C = 320 K
Initial pressure, P₁ = 140 kpa
Final pressure, P₂ = 105 kpa
We need to find the final temperature if the volume remains constant. The relation between temperature and pressure is given by :
or
So, the final temperature is equal to 240 K or -33.15°C.
Yes, it is 80%. Hope this helps!
The percentages of carbon and hydrogen 84.37% and 15.693% respectively.
<h3>What is a molar mass ?</h3>
The mass of a certain chemical element or chemical compound (g) divided by the amount of material is known as the molar mass (mol). By multiplying the standard atomic masses (in g/mol) of the component atoms, one may get the molar mass of a compound.
Molar mass of the compound is the mass of 1 mole of compound which is the sum of masses of each element.
Mass of 1 mole of compound= mass of carbon + mass of hydrogen+ = 9(12) + 20(1)= 128 g.
Percentage by mass of carbon = %
= 108/128 * 100
= 84.37 %
Percentage by mass of carbon = %
=20/128 *100 =15.63 %
The percentages of carbon and hydrogen 84.37% and 15.693% respectively.
